Cairo’s Downtown cinemas were once masterpieces of architecture, screening golden age movies plus witnessing important events. Nowadays, few are still working, while many are ready to be demolished. The best conservation for historic buildings is managing change caused by time. One way to make this happen is smart engaging reuse, thus continue to retain value to current and future generations. Local government and private companies have tried to resuscitate Cairo’s silver screens. This revitalization started with simple face lifting, then developed to rebranding with creative re-use introducing new functions. A key to this creative re-use is across disciplines; new forms of art, music, and media performances. This paper aims to explore four re-use performances bringing the insight of art and media into the field of heritage management. First, “Nassim El Raqs” organized “When dance meets heritage” in Theatre Cinema Eldorado. Second, Radio Theatre re-used to host liveshows; “Al-Bernameg” and “AblaFahita”. Third, Zawya - located in cinema Odeon - launched as the first art-house cinema in Egypt. Last, Teatro Independent Theatre opened their interactive performance “The Metamorphosis” at cinema Elkahira. This paper ends with a framework for rebranding cinemas; comprises both the challenges facing the re-use and proposing community-oriented marketing strategy.
The beginning studio sometimes described as the most traumatic period for the architecture students. Many challenges in visualizing, imagining and comprehending spatial relations over the stages of the design process have been observed. Educators confirmed that spatial ability is central to design studio demands. The main goal of this research is reducing beginners’ obstacles and enhancing design education. A total of 353 first-year architecture students were selected via random sample from three universities in Cairo. The students’ spatial ability skill-level were measured using two spatial ability test instruments. Three scores of the first design course were used in determining the students’ design performance. Inferential statistics, as well as correlation analysis and crosstab chi-square test with SPSS were employed to analyze the research data. The outcomes presented strong significant correlation at (< 0.01) points between students’ spatial ability and students’ design course performance. It has proved that spatial ability is a valid predictor of success in the beginning studio. Also, measuring spatial ability helps to identify students who are not ready for studio requirement. Findings suggest enhancing students’ spatial ability among the all preuniversity education levels and during the preparatory year course subjects. This will increase the probability of success.
An analytical study using finite element modeling is conducted to investigate the structural behavior of rectangular concrete-filled steel tubes (RCFST) under torsion. A comprehensive parametric study is carried out to evaluate the effect of various variables on torsional capacity of RCFST sections. The following parameters are considered; steel strength, steel ratio, and dimensions of steel section. The results are also compared to the design equation presented by the available international codes.
The continuous growth of motorized vehicles and air pollution caused by them, are among the major reasons in which strategies related to transportation and land uses are being implemented enhancing the built environment. This paper introduces approach leading catalytic effects for urban redevelopment through introducing Mobility hubs. According to academic arguments regarding the relation between urban form, built environment and travel patterns, the more urban development around transit stations referred to as transit oriented development (TOD) is compact, the more it contributes to sustainable metropolitan system. Mobility hubs are types of TOD projects, which strive to create opportunities for development. The current research examines the possible role of mobility hubs as anchors in urban regeneration strategies aiming to formulate a model that evaluates hubs' effects on surrounding contexts‘ regeneration. This research is divided into two parts; the first examines the concept of mobility hubs as catalysts to existing urban areas‘ regeneration, the dimensions and elements responsible for the hubs' success as catalytic projects, the second investigates case study for transit station and its context, in Alexandria city, Egypt. The analysis of this case will be through designed model assessing the catalytic effect of the hub on its immediate contexts of value.
The research addresses the concept of dynamism and movement in architecture; also the role of time, the human's eye, and perception to classify it “latent or movement”. In addition, analyzing international projects about the thought of dynamism, and employing the vocabulary of the formation. Because of the thought of some architects in the static of the building, which gives the feeling of boredom. In addition, fixed forms are no longer able to meet the needs of users, especially with the increasing of climatic changes and advanced activities. Besides, the misconception that dynamism is only to move the building without looking for the architectural thought behind it, which depend on definite rules and the designer's experience and practice. Therefore, the aim of the research is to guide and employ the concept of dynamism in design, what governs it from the architectural thought to be interactive dynamic buildings by concluding and formulating a methodology to link and reconcile among opportunities of movement, technology “systems – materials”, the required performance, and the factors affecting. Moreover, determining any types of movement more properly and suitable for the nature of the project to root the concept of dynamism, and to give the building an architectural character.
The aim of this paper is to evaluate the performance of three surface water treatment plants using different filtration technologies. The performance evaluation was based on variations in turbidity, total dissolved solids “TDS” and total solids “TS” as well as micro-organisms counts in raw and filtered water in addition to an economic comparison between the studied treatment processes with different filtration systems following an evaluation of collected data along four years from existing water treatment plants “WTPs” in Menofia Governorate. The main conclusions of results revealed similar performance in removal of turbidity, microorganisms and TS concentration through various filtration systems. Direct filtration system with a declining rate was considered the most economic in operation. The results also indicated that conventional filtration system stands in an intermediate position in terms of economic comparisons. Although pressurized compact filtration system recorded efficiencies same as other systems in terms of removal of turbidity and microorganisms, the system was the least favored in economical comparisons under the studied conditions “e.g. flow, water quality, consumables”.
The following paper deals with investigating the parameters associated with the filtration of ceramic sludge produced in an Egyptian factory producing ceramic tiles. The slurry was filtered using a Buchner funnel fitted with canvas filter medium under five different absolute pressures. The average specific cake resistance and the filter medium were obtained each time. Calculations revealed that the cake was slightly compressible and that the filter medium resistance was independent of the prevailing pressure. From factory data, it was possible to evaluate the required filtration area for disposing of the sludge cake.
The climate of Aswan City is characterized by a hot desert climate. So, the indoor temperature exceeds the thermal comfort through the over-heated period. With this hostile environment, the outdoor spaces suffer from negligence concerning the climatic design. The simulation study, using Autodesk CFD 2016, consists of two models. The first model depends on the current situation of AlSil district in Aswan, while the second model is the modified one. The boundary conditions are placed according to the weather conditions in Aswan City. Then the cooling load was calculated, using the residential heating and cooling load calculation spreadsheet to indicate the efficiency of the energy consumption in a multi-story residential building. The simulation results of the modified model show a significant decrease in the outdoor temperature by nearly 7°C, and the indoor temperature dropped from 4°C : 9°C. On the other hand, the cooling load was decreased by almost 17.7% : 22.5% according to the building floor site.
An asymptotic description of dispersion in stratified aquifers using the center manifold theory is presented. The system is assumed to evolve slowly in time and space thus allowing the center manifold approach to be applicable. The spatial variability in the process is accounted for by using spatially variable conductivity and dispersion coefficients. The approach presented herein focuses on longitudinal dispersion in the direction of mean flow. An important advantage of the proposed approach is that higher order asymptotically correct approximations are easily obtained once the first approximation has been derived. In addition, the approach yields a onedimensional ordinary differential equation that can be easily solved in comparison with the two-dimensional advection dispersion equation. The predictions of the center manifold equations closely match the observed spatial moments for the Cape Cod tracer experiment of Massachusetts, USA.
Urbanization growth shows an unexpected increase during the last decades, since cities sprawled to fulfill their population growth needs, pollution and overexploitation of resources are increasing too. Many solutions were introduced to decrease the impacts of pollution towards our planet, like using renewable and clean sources of energy, recycling of solid wastes, increasing people awareness, which isn't applicable everywhere. Eco cities were introduced as an integrated sustainable development approach towards the urban areas and their natural environment. This approach applied through many sustainable indicators in different European and American cities like Stockholm and San Francisco, but can Eco-cities be applied in developing countries? What did Curitiba city in Brazil do to be an eco-city? Discussions occurred towards the global warming as a result of increasing global urbanization rates, the main global sustainable city indicators, and an analytical study through selected indicators applied in Curitiba and ends with an analytical SPSS study for selected sample of cities and indicators to categorize the indicators according to their strength, and cities according their scores for their sustainability with analytical view towards developing countries.
